Brain response to sleep-related attentional bias in patients with chronic insomnia

Authors: Xi-Jian Dai


Patients with chronic insomnia, prevalent in 10–15% of the adult population, who underwent the subjective experience of chronically disturbed sleep, sleep loss, non-refreshing sleep, and heightened arousal in bed with impaired quality of life, showed a decreased ability to disengage from external information processing at sleep on-set (1-3). They frequently experience intrusive thoughts, described as worrisome and negatively toned, and paid too much attention to sleep-related information.
